Abstract

Stroke is a brain disease occurs when blood stops flowing to any part of the brain, damaging brain cells and causes joint stiffness. By doing continuous passive motion (CPM) exercise, the joint stiffness can be reduced and it helps maintaining the range of motion (ROM) of the joint. Portable Elbow Joint Device (PEJD) will provide CPM exercise to patients with Neurological problems such as stroke and traumatic brain injuries that affected the arm. Existing devices of the elbow rehabilitation therapy are large, complex and difficult to be carried anywhere. The upgrading of PEJD focuses on reducing cost, ensuring comfort, and making it portable and light in weight. Besides, PEJD will assist stroke patients in involuntary progressive muscles weakness. A Gear Motor w/Encoder, model No. GB37Y3530-12V-83R is used to move the arm/elbow joint and its angle in controllable speed, timer by using Arduino Nano (microcontroller). The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0. A rechargeable battery is added on the device to enable the device to operate using DC power supply. The innovation of PEJD will benefit the stroke and elbow injury patients during rehabilitation process as the angle is adjustable, count and speed buttons are also available for such therapy treatment.
